Review: These PSU's are great (and that's coming from a former repair shop owner). - Recently retired from owning a computer repair shop for several decades. Have been messing with electronics and computers for over four decades now. Anyway, I've been a fan of these SeaSonic PSU's for years. And I'm still buying them for my own projects in retirement. I have worked on more PSU's than I care to remember. And I have tried a lot of different PSU's in my and my customers' builds over the years. For a long while I preferred PSU's from PC Power & Cooling, but in the past decade or so Sea Sonic has pulled ahead. They are my top pick now. SeaSonic sells good heavy PSU's with good components. They've been around since 1975 and it shows in their PSU's. I have some 18 year old PC Power & Cooling PSU's that have had near-constant use year after year and they just keep going. I keep moving them into new projects and just adding adapters/connectors if needed. They're great for legacy builds or Linux builds. Anyway, I expect to get the same longevity out of my SeaSonic PSU's. Also in my top 5 are Corsairs, CoolerMasters, and on occasion SilverStones (when there's a sale or I can't get what I want in a SeaSonic or PC Power & Cooling for a decent price). Not all PSU's from a company are the same. Especially if they outsource manufacturing here and there. Do your research on specific models that fit your intended project. Always buy more power than you need. And always keep all computers on a UPS (uninterrupted power supply). You'll be able to keep your PSU's going a lot longer if you do that. And just so you know, all the companies I stick with are also capable of producing stinkers. I just think they do so less often. All-in-all though, top end SeaSonics have never let me down. My brother likes them too and he's been working in computers longer than me AND is ten times the computer guy than I'll ever be. Review: Impresiona su calidad-precio. - Vale, que si. Que ahora Seasonic en los modelos S3 lleva capacitadores Teapo, que es una marca taiwanesa, y es mejor tener un capacitor principal japonés aquí como Nippon-Chemi Con o Rubycon... Pero sigues teniendo 5 años de garantía y son de 105º, no 85º y chinos como otras fuentas igual o mas caras que ponen gaming o ventiladores rojos... La calidad de construcción general es bastante buena para una fuente de alimentación económica, pero esta es la clave. Si la de 550w está a 46€ y la de 650w esta a 55€, no hay mejor fuente por ese precio. Subir a 88€ supongo que habrá sido por el arreón de ventas que ha tenido la S3 650w, que es algo mejor en términos de calidad. Aunque la 550w a ese precio es muy interesante. Por 88€ ya te vas a una plus gold, la que sea. ¿Qué equipo usar ahora para estas fuentes? Pues te vale cualquier combo Xeon e5 - placa china que quieras montar y no tener problemas. Los rusos los ponen un gtx 1080ti y la fuente ni se entera. Asi que si eres un usuario gaming normal, esto es un ryzen 5 y una gtx 1660 o rtx 2060... Estas fuentes no van estar ni a la la mitad de su potencia de trabajo. Si encontráis una fuente atx que de 500-650w reales con cinco años de garantia, cables planos, válida para 110v-230v... Avisad. Yo mientras estén en 45-55€ los dos modelos de 550w-650w voy a seguir montando estas. Si suben las dos de precio, gigabyte 650w plus bronce. Editado en lunes 3 octubre 2022.

Thanks.** A: Absolutely not. The seasonic psu is standard atx form factor (think sorta cube-like) and the 9010 is a small form factor PC which uses a proprietary PSU that is very long and thin. In theory you could run it outside of the case and cut holes to the inside for the cables but that is very messy and definitely is not "fitting". **Q: Can this fit in dell optiplex 980 mini tower?** A: Heh, I suspect you won't find an answer to that. the answer is possibly, it depends on whether the Dell uses industry standard dimensions, mounting points, and motherboard connections. This power supply is ATX standard and I have installed standard ATX in some Dells. You can compare what you have to images on the internet of standard motherboards and cases and see if they look the same. The correct 4 screws at the back to hold the power supply and that the motherboard connectors have the right number of wires and look like the right style of connector. ## Customer Reviews ### ⭐⭐⭐⭐⭐ These PSU's are great (and that's coming from a former repair shop owner). *by D***K on 15 December 2021* Recently retired from owning a computer repair shop for several decades.
